Release 2.0.0

What's Changed

• complete API rewrite
• added support for more label types: all arithmetic types + strings
• added Python3 bindings
• added the new plssvm-scale executable
• the used real (float vs double) and label (int vs string) types can be selected using a command line flag
• added optional, automatic performance tracking to yaml files
• LIBSVM conformance: features are not expected to use 1-based indexing instead of 0-based indexing
• added the option to provide the maximum number of CG iterations as a command line flag
• added support for memory-mapped IO under Windows
• improved IO performance for the LIBSVM file format
• added git metadata information
• added a new verbosity output mechanism to enable a LIBSVM-like terminal output
• if not provided, add custom find_package cmake files for the PLSSVM dependencies
• improved documentation
• added examples
• drastically improved test coverage
• improved Jenkins CI
• minor bug fixes

Full Changelog: v1.2.1...v2.0.0

Release 1.2.0

What's Changed

• a new backend arrived: now HIP is also supported!
• now multiple SYCL implementations can be used in one binary; no need for two binaries to test DPC++ and hipSYCL anymore!
• fixed an issue inside the CG implementation of our OpenMP backend resulting in a factor of 2 runtime improvement
• add a custom mechanism to cache the JIT-compiled OpenCL kernels; now caching works on every hardware platform!
• improved the performance of some IO parts
• added a manpage entry for plssvm-train and plssvm-predict
• reduce code duplication by factoring out common code to a gpu_device_ptr base class
• the PLSSVM_TARGET_PLATFORMS option is no longer required during the CMake invocation!; its value is now automatically derived using a Python script (needs additional Python packages)
• many minor improvements, quality of life changes, and bugfixes
